What Sefico Nexia does

Nexia S&A (formerly Sefico) is a Paris-headquartered, independent professional services firm founded in 1958, providing audit, accounting and financial expertise, financial advisory (M&A, transaction services, restructuring), operational advisory (outsourcing, transformation, risk management, sustainability), and tax & legal services to French mid-sized enterprises (ETI) and growth-stage SMEs, as well as family-owned groups and French subsidiaries of international corporates. The firm operates through approximately 640 professionals across six French offices — four in Paris plus Lyon, Montesson, and Argenteuil — with the Lyon location opened in early 2026 representing its first expansion beyond the Île-de-France region. Its core product portfolio is delivered through five service lines, supported by a wholly-owned in-house law firm (Nexia S&A Avocats) and the Nexia S&A Hub digital client portal.

The firm's business model is engagement-based professional services revenue, with pricing structured per scope, complexity, and duration and contracted on multi-year retainers for recurring audit, accounting, and BPO work alongside project-based M&A and restructuring fees. Go-to-market is sales-led and partner-driven, emphasizing a 48-hour response commitment and direct senior-associate engagement, with sector specializations spanning audiovisual, asset management, family offices, hospitality, private education, and more. Distribution is direct-to-client across French offices, complemented by cross-border capability via membership in the Nexia International Network — a confederation of 497 independent member firms across 120+ countries representing 23,578 professionals and $2.7B in combined 2025 revenue.

Revenue of €75.1M in the most recent disclosed period (up 9.6% from €68.5M, which itself grew 11.7%) places the firm in the French mid-tier professional services bracket. There is no proprietary technology platform disclosed, no funding rounds, no M&A activity, and no equity-backed ownership structure — Nexia S&A appears to be partner-owned and managed, with the international Nexia network functioning as a non-equity strategic alliance rather than a parent entity.
